RemoteCentral.com
I would suggest that you take a look at remotecentral.com. To quote from the home page of the site...
"This site is designed to be the ultimate online source for information on mid- to high-end home theater remote controls with reviews, complete specifications, operating tips and user-to-user message boards on the latest and greatest products on the market. Remote Central also features DVD movie reviews, tips and other general information on working with remote controls plus a comprehensive archive of downloadable files."
One of the forums on the site is dedicated to the Home Theater Master remote controls. There is also a file area where you can download .mxd and .mxf files for the Home Theater Master remotes.
Discrete codes are a wonderful thing for macros on your remote. Non-discrete codes work as toggles. The Power code will turn on a device if it is off and off if the device is on. A discrete ON code will only turn the device on, if the device is off it will turn on if it is on it will stay on.
I have discrete power codes for all of the equipment in my ht system except for my 721. I also have discrete codes for every input on my TV and on my stereo receiver. This allows me to program a "HDTV" button that turns on my TV, turns on my 6000, turns on my stereo receiver, switches the tv to video input 5 (HD component input) and switches the stereo receiver to the MD/DAT input (6000 digital audio connected to this input) when I press this one button.
BTW Scott, do you know if discrete power codes are included in the upcoming update for the 721?
